During recent years,International Nephrology and Emergency Medicine Association preferred a cute kidney injury( AKI)rather than a cute renal failure for the diagnosis and intervention in the early phase of AKI,with the ultimate goal of reducing the mortality rate.It is not sensitive to diagnose AKI in the early phase only according to the change of urine output and serum ereatinine.It is reported that some new biomarkers are sensitive and specific and may play important roles for the early diagnosis of AKI.

Objective To investigate the serum proteomic patterns in lung cancer by surface enhanced laser desorption/ionization-time of flight-mass spectrometry (SELDI-TOF-MS) techniques and build diagnostic models in order to evaluate their clinical significance by biomarkers screening in lung cancer.Methods SELDI-TOF-MS and CM-10 protein chip were used to detect the serum proteomic patterns of 38 lung squamous cell carcinoma and 30 lung adenocarcinomas,including the comparation in 34 geminate patient serums before and after surgery.Nagative control setted as a group of 50 normal tissues.BioMarker Wizard and BioMarker pattern system software were used in combination to analyze the data and to develop diagnostic models.Results Two protein peaks from a total of 167 were chosen as a biomarker pattern in the training set.Two protein peaks pattern (mass/charge ratio [m/z] 6 010,5 330) was observed in the model that could be used as to distinguish lung cancer from non-cancerous diseases.It yielded a sensitivity of 98 ％ and a specificity of 96 ％.There were 9 different protein peaks (P ＜ 0.05) between pre-surgery and post-surgery.There were 8 different peaks (P ＜ 0.05) between metastasis and non-metastasis.Conclusion SELDI techniques can be employed as diagnosis in lung cancer patients with relatively high sensitivity and specificity,and also could be used as an effective tool for the screening of lung cancer.

Next-generation sequencing (NGS) technologies have improved as well as the costs have gradually decreased in the detections of genetic diseases. This article describes the principle, platform, and data analysis of NGS and the application of NGS technologies to the molecular diagnosis of hereditary hearing loss (HL). The use of NGS technologies makes the discovery of HL genes more feasible than ever. And the data obtained by NGS used in genetic counseling for clinical practice may assist in defining genetic profiles of HL individuals and expedite the pace of personalized medical care.

The challenges posed by norovirus infections to global health are increasing accompa-nied by the rapid rate of the genetic and antigenic evolution of circulating noroviruses. Due to lack of in vitro culture cells and small animal models, norovirus vaccine cannot be prepared by using traditional techniques. With the in-depth understanding and study of norovirus, the subunit vaccines against norovirus infection based on P particles have been developed and presented the characteristics of easily expressed, low cost, high immunogenicity, stable structure and so on. In addition, norovirus P particle has been used as a subvi-ral nanoparticle for vaccine development against other viruses and for antibody production against chronic dis-ease ( Alzheimer′s disease) , which benefits from the accommodation of foreign antigens in the three loops of P particle. In this review, we describe the progresses in the field of P particle related vaccines for providing suggestions about the research and development of multivalent vaccines in China.

Fever was induced by ET in rabbits. The PGE_2 level in the plasma and cerebrospinal fluid (CSF) was measured at peak of fever in both electric acupuncture and control group. The results showed that when the body temperature of animals rose to the peak, the PGE_2 levels in the plasma and CSF were higher than that before fever. (P

[Objective]To evaluate the outcome inforation provided by two scoring systems after operative treatment of elementary posterior wall fractures of the acetabulum.[Method]Thirty-two patients with elementary posterior wall fracture of the acetabulum were included in the study.Functional outcomes were assessed with use of the eight health dimensions of the short form(SF)-36,and clinical outcomes were evaluated with use of the modified Merle d' Aubign? score.The SF-36 scores were compared with previously reported normal values and the correlation was analyzed between the modified Merle d' Aubign? score and score of each SF-36 health dimension.[Result]The mean modified Merle d' Aubign? score was 16.28 (range 13-18,SD 1.3),indicating overall good-to-excellent clinical results.However,all SF-36 health dimensions were significatly lower than the expected forms,with a significant statistical difference(P

Objective To constitute a higher expression system and to obtain the breast cancer cell strains in which BSP is stably expressed. Methods hBSP gene was subcloned from pB-hBSP vector by PCR. The PCR fragment was inserted into the eukaryon expression vector, pIRES2-EGFP, which allow exogenous protein and EGFP to express respectively. The recombinant vector, pIRES2-hBSP-EGFP, was transfected into human breast cancer cells with Lipofectamine TM 2000. The expression of symbol protein EGFP, could be conveniently observed with fluorescent microscope. Results The recombinant pIRES2-hBSP-EGFP plasmid was constituted and successfully transfected into breast cancer cells. In the breast cancer cell strain hBSP and EGFP were expressed. Conclusion The successful constitution and transfection of hBSP and EGFP nonfusion expression vector laid a foundation for the further study on the effect of BSP on breast cancer metastasizing to bone in vivo or in vitro.
